Xen Project 4.8 Acknowledgements
|
Note that the Acknowledgements have been created based on 4.8.0-rc8 as the author of this page will likely be on vacation during the release. This means that a small number of contributions may be missed. |
Overview
As we have made significant changes to the xen source tree structure, we will count acknowledgements in line with RFC Xen 4.6 Acknowledgements.
The following table compares Xen 4.7 with Xen 4.8. We also cover changes to Xen only components in Linux, FreeBSD, NetBSD and QEMU in the "Drivers and Devices" column, which are primarily made by Xen Project developers. Note that the number is not part of the 4.8 Hypervisor Total.
